I received the following question from one of our loyal readers, and thought it would be a good idea to respond to it via the blog so we can all learn together.
We found a box(wood)with 25 silver stamps of royalty collection.
This is the 1s 3d coronation stamp of 1953. It says the queens
jubilee. The same thing we found in gold (plated).
The paper with it says “The Africana Commemorative Mint”.
We would like to know if it is worth something.
Thank you,
Cora S.
Thanks Cora for your inquiry. 
These gold and silver postage stamps replica were produced by the Africana Commemorative Mint in 1977 to commemorate the Queen’s Silver Jubilee. They are housed in a velvet-lined satinwood-inlaid wooden display case, inclusive of a certificate of authenticity. Cast from STG-grade sterling silver, they are plated in 24 carat gold.
In reference with market value, here are some selling prices I found on the Web:
